I kind of miss the ludicrous demises of villains in old James Bond movies. Oddjob getting electrocuted by his hat. Goldfinger getting squoze out the airplane window. Inflated Kananga. Mr. Kidd en fuego. Etc. There's some of that here, but it's mostly people getting shot in the face.
The opening scene has a (very) young Madeleine Swann in peril from a killer in a Noh mask. She does quite a bit of damage, and only survives due to luck and unexplained mercy. Flash forward to years later when she's taken up with James Bond (it helps to be able to remember the details of their relationship in the previous movie, Spectre). At one point, Bond tells her "We have all the time in the world."
Aw, man. As viewers/readers of the movie/book On Her Majesty's Secret Service may remember, that's a line that doesn't bode well for a long-lasting relationship.
But in any case, their relationship is complicated by their mutual secret-keeping. It gets a little worse when Bond gets targeted by an army of assassins. He prevails (it's the beginning of the movie, after all), but is a little nonplussed that the bad guys were able to find him so easily, when only he and Madeleine knew they were going to be there. He suspects betrayal, and sends her off to Dumpsville on a train.
Jump to five years later, Bond is living the retired-spy life in Jamaica. When his old buddy Felix shows up asking for some help with tracking down a rogue bio-warfare researcher. Who's previously been shown to be in cahoots with bad guys. And…
Well, there's a lot going on. No further spoilers. I liked it OK. Very long, so plan your urination appropriately if you see it in the movies.
